Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an oil and fat solubilized product having an antioxidant effect on feed and edible oils and fats.

"Solubilization" in the present invention includes all solubilization, microemulsification, and emulsification.

[Conventional technology]

Traditionally, ethoxyquin (6-nitoxy1,2-dihydroq-2,2-,4-trinotylquino/) has been mainly used as an antioxidant for feed, but there has been some controversy regarding its residual properties, and it has been criticized. A product with high safety is desired in terms of regulations (>150 ppm).In addition, BH, an anti-inflammatory agent widely used in foods such as fats and oils and dried sardines, is desired.
A (diptyl-4-hydroxy-7-nisole) has also been reported to be suspected of causing cancer, and its use in food products is expected to be banned in the near future, and related industries are already refraining from using it. Both ethoxyquin and BHA are industrially synthesized, which is contrary to the social trend toward natural products. Under these circumstances, there was a need for safe and powerful antioxidants made from natural products.

[Problem that the invention seeks to solve]

As a natural antioxidant, gallic acid obtained by hydrolyzing tannic acid, a plant component, is known to have strong antioxidant effects, but it is soluble in fats and oils. About 300 ppm only in the thighs! It cannot be erased, requires heating, requires considerable time and effort, and has the disadvantage that it is colored blue to black when it comes into contact with divalent iron ions.

[Means for deciding between points]

The idea of the present invention is that gallic acid is a food hygienically safe substance;
In addition, we have found that it has a strong antioxidant effect, brings out the synergistic effect of the anti-bust effect, and can also prevent coloring with divalent iron ions. The development was successful.

That is, the present invention provides a solubilized fat and oil having an antioxidant effect, which is composed of gallic acid, a polyhydric alcohol, an emulsifier, and a fat, and optionally contains citric acid and/or L-7 scorbic acid. be.

The fat and oil solubilized product of the present invention contains gallic acid at 5 to 25 weight-1:
%, citric acid and/or L-7 sfulvic acid from 0 to 3
A preferred blending ratio is 50 to 80 parts by weight of a polyhydric alcohol phase containing 0% by weight and 20 to 50 parts by weight of an oil phase containing 5 to 15 parts by weight of an emulsifier.

As the gallic acid used in the present invention, ordinary commercially available products can be used. If the amount is less than 5% by weight, the desired antioxidant effect cannot be obtained, and if it exceeds 25% by weight, it may cause damage to fats and oils. It is difficult to dissolve.

The polyhydric alcohol used in the present invention is an alcohol having two or more hydroxyl groups, and preferably has a low viscosity in order to solubilize gallic acid, such as propylene glycol,
Glycerin, sorbitol, etc. can be used.

Among them, polyglycerin fatty acid esters are particularly preferred. Polycrycerin pilgrimage 11h
The acid 1 ester is an esterified product of polymerized y2-122-12 double glycerin and a fatty acid having 10 to 2 carbon atoms, and the ester having an HLB of 1 to 7 is preferably used.

As the fats and oils used in the present invention, all general and natural blooming oils can be used, but in order to obtain a good solubilized fat, K is preferably a liquid oil, examples of which include soybean oil, rapeseed oil, sunflower oil, cottonseed oil, etc. There is.

The fat and oil solubilized product of the present invention preferably has a blending amount within the above-mentioned predetermined range, and if it deviates from this range, a good fat and oil solubilized product having an excellent antioxidant effect cannot be obtained.

In order to obtain the fat-and-oil solubilized product of the present invention, a predetermined amount of the polyhydric alcohol phase and the fat-and-oil phase may be thoroughly combined and solubilized using a common emulsifying device such as a homomixer or a homogenizer.

〔Effect of the invention〕

The solubilized fat and oil having an antioxidant effect of the present invention can easily solubilize gallic acid, which is safe from a food hygiene perspective, in fat and oil.

By adding the product of the present invention to feed fats and oils, deterioration of the preparation can be suppressed, and it can also be widely used as an antioxidant for general edible fats and oils such as margarine, shortening, and flying oil.

〔Example〕

Practical development 1 White rapeseed oil prepared by dissolving 125y of glycerin, 25y of gallic acid, and 25y of benic acid, and 6 of polyglycerin fatty acid ester (@combined silt, degree of polymerization 6).
50y and emulsified using homo2xer, /I61-9
An oil and fat solubilized product was obtained.

Its antioxidant and effective A, O, M, (Active Ox
ygenMethod). The results are shown in Table 1.

Established.

The amount of mecitric acid 1, L-7 scorbic acid added is % by weight based on glycerin.

As is clear from the results in Table 1, oxidation is clearly suppressed in the purified lard to which the oil and fat solubilized product having an antioxidant effect of the present invention is added, and it has an excellent antioxidant effect compared to BHA. It turns out that there is. The additive effect of adding citric acid and L-ascorbic acid is clear.

In addition, each sample oil to which the above-mentioned oil and fat solubilized substances were added was subjected to a coloring test using aqueous chloride 2S solution, and visual judgment was performed, and 41 was slightly colored, but no coloring was observed in all the others. .

Example 2 A solution of 20 y of gallic acid and 5 y of citric acid dissolved in 100 y of sorbitol (containing 70%), 4 y of sucrose fatty acid ester (HLB3) and 4 y of glycerin fatty acid ester (
80 y of rapeseed white oil in which HLB4)37 was dissolved was emulsified using a homomixer. When the antioxidant effect and effectiveness of A, O, and M were measured by the same method as in Example 1,
It was 71 hours.

Example 3 15 y of gallic acid and 5 y of citric acid were dissolved in propylene glyfur 100F, and 40 y of white soybean oil in which 5 y of polyglycerin fatty acid ester (degree of polymerization: 4; HLB 6) was dissolved were emulsified using a homomixer. . The antioxidant effect of A, O, and M was measured in the same manner as in Example 1 and was found to be 67 hours.

Example 4 60 parts by weight of a glycerin phase obtained by dissolving 5 parts of ethoxyquin (relative to glycerin) in beef tallow for feed heated to 60C and 4 parts of a rapeseed oil phase containing 5 parts of polyglycerin fatty acid ester (same as Example 1) emulsified by weight part with a homomixer] and the purity of gallic acid was 0.02 kg and 0.05 g.
Samples were prepared with % wt. Additive-free feed-grade beef tallow (10y) to 200* for each sample oil and comparison product
The samples were collected in an Erlenmeyer flask with a stopper, placed in a 60 tZ' constant temperature bath (in the dark), and measured for peroxide values (p, o, v) after 1 month, 2 months, and 3 months. . The results are shown in Table 2.

Table 2 As shown in Table 2, the beef tallow for feed to which the oil and fat solubilized product of the present invention has been added can suppress the increase in peroxide value due to long-term storage and is extremely stable, even compared to ethoxyquin. It can be seen that the product of the present invention has excellent antioxidant ability.
